LSD
(blotter, tab, acid, lucy)
LSD (lysergic acid diethylamide) is a psychedelic drug that was first synthesised by Albert Hofmann in 1938. Its psychedelic properties were discovered in 1943 when Hofmann accidentally ingested some and had a now iconic bike ride home. LSD generally comes absorbed onto a small square of paper and is sometimes available as a clear, tasteless liquid or dropped onto sweets/sugar cubes.

Harm Reduction Advice
- Acid can take a while to kick in, anywhere between 30 minutes to an hour, so avoid re-dosing within this time, even if the effects aren’t as strong as you’d expected.
- Acid lasts a long time (12ish hours), so factor this in before you take it.
- Think about your set and setting. If you’re not in the right headspace, or not feeling comfortable in your environment, save your trip for another day.
- Sometimes acid can be overwhelming, or you can experience a ‘bad trip’. It can be helpful to have a ‘trip sitter’, someone who remains sober, who can provide support and reassurance, and get help if necessary.
- Use with people you know and trust in a calm, safe environment, especially if you’re new to psychedelic drugs.
- You’re likely to feel depleted after using drugs. Hydrate, eat something nutritious and rest. Click here for more information on taking care of yourself after a session.
- Mixing drugs, including alcohol, can be risky. Mixing acid with other drugs with psychedelic properties (e.g. ket, shrooms, 2C-B, cannabis) can lead to an overwhelming experience. Click here for more information on drug combinations.
- More physically harmful substances such as the NBOMBe series are sometimes sold as LSD. Acid is tasteless, so if a tab has a chemical taste, spit it out (if it’s bitter, it’s a spitter).
- We recommend you always test your drugs, for information on testing services in Bristol, click here.
- If you’re out and about, make sure you and your mates have a safe way to get home, definitely don’t drive.
